Socialisme ou Barbarie

Socialisme ou Barbarie (Socialism or Barbarism) was a French-based radical libertarian socialist group of the post-World War II period (the name comes from a phrase Friedrich Engels used, and was cited by Rosa Luxemburg in a 1916 essay, 'The Junius Pamphlet'[1]). It existed from 1948 until 1965. The animating personality was Cornelius Castoriadis, also known as Pierre Chaulieu or Paul Cardan.[2]
